On the otherhand, one end of the spring contacts the key cap 141, and the other endof the spring contacts a bottom part of the telescopic cover.

In the present embodiment, the sliding plate 130 includes a plat portion131 and a recess portion 132 that are arranged side by side, there maybe a plurality of recess portions 132, and the quantity of the recessportions 132 is equal to the quantity of the key structures 140 a.Specifically, the reciprocating element 142 is located on a sliding pathof the plat portion 131 and the recess portion 132. As shown in FIG. 1B,when the display 120 is opened relative to the host 110, thereciprocating element 142 contacts the plat portion 131, and the key cap141 is higher than the operating surface 111. Therefore, a sufficientpressing stroke can be provided for the user, thereby improvingoperation experience of the user.

As shown in FIG. 2B, when the display 120 covers the operating surface111 of the host 110, the sliding plate 130 slides to make the second end142 b of the reciprocating element 142 move away from the plat portion131 and move into the recess portion 132. At the same time, the key cap141 sinks along with the reciprocating element 142 to make the key cap141 be lower than the operating surface 111. Therefore, the keystructure 140 a can be prevented from being squeezed by the display 120covering the operating surface 111 of the host 110, thereby improvingthe service life of the product.

In particular, a direction in which the key cap 141 sinks along with thereciprocating element 142 is perpendicular to a sliding direction of thesliding plate 130.

Referring to FIG. 1A and FIG. 1B, in the present embodiment, theelectronic device 100 further includes a rotating shaft 150, and thedisplay 120 is pivoted to the host 110 by using the rotating shaft 150.In detail, the rotating shaft 150 includes a driving portion 151 locatedin the host 110, and the driving portion 151 is mechanically coupled tothe sliding plate 130.
